Abstract: A medical scalpel system includes a safety handle and an internal mechanism that permits a blade to be extended and retracted relative to the safety handle. At least a portion of the system is manufactured pursuant to a process wherein a material, such as silicone or Teflon, is used in the manufacturing of the components to provide a smooth movement between components of an extension and retraction mechanism.

Abstract: A surgical blade includes a region that has a mirror finish such that the blade can reflect an image that can be viewed by a user. A first portion of the blade is a sharpened edge and a second portion of the blade has a mirror. The mirror portion of the blade can be useful in situations where visualization can be facilitated by using a mirror at or near the region where the blade is used. Upon identification or visualization of the region to be incised, a user can create an incision using the first, sharpened portion of the blade.

Abstract: A composite biocompatible hydrogel material includes a porous polymer matrix, the polymer matrix including a plurality of pores and providing a Young's modulus of at least 10 GPa. A calcium comprising salt is disposed in at least some of the pores. The porous polymer matrix can comprise cellulose, including bacterial cellulose. The composite can be used as a bone graft material. A method of tissue repair within the body of animals includes the steps of providing a composite biocompatible hydrogel material including a porous polymer matrix, the polymer matrix including a plurality of pores and providing a Young's modulus of at least 10 GPa, and inserting the hydrogel material into cartilage or bone tissue of an animal, wherein the hydrogel material supports cell colonization in vitro for autologous cell seeding.

Abstract: A scalpel having a sharpened edge and a coupling region that is configured to be removably attached to a handle. At least a portion of the scalpel is made of a material that is malleable such that the shape of the scalpel may be modified to provide a shape that improves accessibility to a surgical site.

Abstract: A computer implemented method comprising the steps of: detecting a user selection of a plurality of visual representations of data associated with at least partially different sources of data, enabling a user to move the location of at least one of the selected visual representation of data on a display, and thereby to move an active area associated with it, generating a new visual representation of data, and displaying the new visual representation of data, wherein the step of generating is performed after a user has moved at least one of the selected visual representations of data, and an active area associated with it, so that the moved active area overlaps an active area associated with another of the selected visual representations; the step of generating is at least partially in response to the overlap of active areas of selected visual representations; and the new visual representation of data is based on/represents data represented/displayed in the selected visual representations of data which have ov

Abstract: An electrically conductive cellulose composite includes a cellulose matrix and an electrically conductive carbonaceous material incorporated into the cellulose matrix. The electrical conductivity of the cellulose composite is at least 10 ?S/cm at 25° C. The composite can be made by incorporating the electrically conductive carbonaceous material into a culture medium with a cellulose-producing organism, such as Gluconoacetobacter hansenii. The composites can be used to form electrodes, such as for use in membrane electrode assemblies for fuel cells.

Abstract: The present invention relates to a connection system for use with an active or passive protection device that minimizes weight. In accordance with the present invention, a single stem connection system for use with an active protection device includes a single bent cable that is attached to the single cable terminal of the active protection device. A stem tube is fitted over a portion of the bent cable giving the appearance and benefits of a single stem. However, a portion of the bent cable is left separated thereby automatically forming a clip-in point for the entire active protection device. Unlike conventional single stem connection systems, the single stem system in accordance with the present invention only requires coupling the cable to the cable terminal thereby reducing manufacturing cost and minimizing overall weight. Alternatively, a similar connection system can be used with a passive protection device to provide many of the same benefits.
